Under the proposed transaction, Patronus will receive a 19.6% shareholding in Greenvale (valued at ~$5.5M) along with a Board position and a right to support the growth of a dedicated uranium exploration company with a district-scale 2,466km2 uranium exploration portfolio in the premier Pine Creek Orogen uranium province within the Northern Territory. Patronus Resources’ Managing Director, John Ingram, commented: “The sale of the uranium exploration rights to Greenvale will provide the uranium exploration impetus that this region deserves in a dedicated uranium exploration entity and allow Patronus to focus on its gold and base metal interests across the Pine Creek region. The retention of a significant interest in the shareholding of Greenvale is recognition of the belief that Patronus has in the assets and people of Greenvale and sits well with the strategic investment thesis for Patronus”. Uranium Exploration Rights Terms Under the terms of the binding term sheet: Grant of rights: Patronus will, upon satisfaction of the conditions, grant exclusive uranium exploration and development rights over the tenements for up to 20 years. Greenvale will have priority access for uranium exploration activities across the Thunderball Prospects until 31 December 2027. In all other cases, Patronus has priority in cases of conflicting exploration activities. Consideration: Greenvale will provide Patronus with Consideration Shares as consideration for grant of the Uranium Rights for the Pine Creek Uranium Project. Subject to necessary approvals (including shareholder approval under the ASX Listing Rules), Greenvale will issue 144,736,842 ordinary shares to Patronus or its nominee, at an issue price of $0.038, the total consideration being AUD$5.5M. Based on the Greenvale capital structure on 6 June 2026, it is expected that Patronus will have a 19.6% shareholding interest in Greenvale once the Consideration Shares have been issued. Future Capital Support: For 24 months Patronus will have the right to a reasonable opportunity to participate pro rata in any proposed equity capital raising. Board Representation: Patronus will have the right, but not the obligation, to nominate one person for appointment as a Non-Executive Director of Greenvale; the nomination right will continue until such time that Patronus’ voting power in Greenvale is less than 10% for two consecutive months.

Mineral Resources – Base Metals Iron Blow Mineral Resource Iron Blow Mineral Resources by JORC Classification as at 03 May 2017 estimated utilising a cut-off grade of 1.0 g/t AuEq. See ASX:PNX release ‘Hayes Creek Mineral Resources Exceed 1.1Moz Gold Equivalent’ 3 May 2017 for details. Mt Bonnie Mineral Resource Mt Bonnie Mineral Resources by JORC Classification as at 08 February 2017 estimated utilising a cut-off grade of 0.5 g/t Au for Oxide/Transitional Domain, 1% Zn for Fresh Domain and 50g/t Ag for Ag Zone Domain. See ASX:PNX release ‘Upgrade to Mt Bonnie Zinc-Gold-Silver Resource, Hayes Creek’ 9 February 2017 for details. Hayes Creek Mineral Resource (Iron Blow + Mt Bonnie) Notes: Due to effects of rounding, totals may not represent the sum of all components. Metallurgical recoveries and metal prices have been applied in calculating zinc equivalent (ZnEq) and gold equivalent (AuEq) grades. At Iron Blow a mineralisation envelope was interpreted for each of the two main lodes, the East Lode (Zn-Au-Ag-Pb) and West Lode (Zn-Au), and four subsidiary lodes with a 1 g/t AuEq cut-off used to interpret and report these lodes. At Mt Bonnie Zn domains are reported above a cut-of grade of 1% Zn, gold domains are reported above a cut-off grade of 0.5 g/t Au and silver domains are reported above a cut-off grade of 50 g/t Ag. To assess the potential value of the total suite of minerals of economic interest, formulae were developed to calculate metal equivalency for Au and Zn. Metal prices were derived from average consensus forecasts from external sources for the period 2017 through 2021 and are consistent with those used in PNX’s recently updated Mt Bonnie Mineral Resource Estimate. Metallurgical recovery information was sourced from test work completed at the Iron Blow deposit, including historical test work. Mt Bonnie and Iron Blow have similar mineralogical characteristics and are a similar style of deposit. In PNX’s opinion all the metals used in the equivalence calculation have a reasonable potential to be recovered and sold. PNX has chosen to report both the ZnEq and AuEq grades as although individually zinc is the dominant metal by value, the precious metals are the dominant group by value and will be recovered and sold separately to Zn. The formulae below were applied to the estimated constituents to derive the metal equivalent values: Gold Equivalent (field = “AuEq”) (g/t) = (Au grade (g/t) * (Au price per ounce/31.10348) * Au recovery) + (Ag grade (g/t) * (Ag price per ounce/31.10348) * Ag recovery) + (Cu grade (%) * (Cu price per tonne/100) * Cu recovery) + (Pb grade (%) * (Pb price per tonne/100) * Pb recovery) + (Zn grade (%) * (Zn price per tonne/100) * Zn recovery) / (Au price per ounce/31.10348 * Au recovery) Zn (%) Pb (%) Cu (%) Ag (g/t) Au (g/t) ZnEq (%) AuEq (g/t) Indicated 2.08 5.49 0.91 0.30 143 2.19 13.39 10.08 Inferred 0.45 1.11 0.18 0.07 27 1.71 4.38 3.30 TOTAL 2.53 4.71 0.78 0.26 122 2.10 11.79 8.87 Contained Metal 119kt 18kt 7kt 9.9Moz 171koz 298kt 722koz Tonnes (Mt) Grade JORC Classification Zn (%) Pb (%) Cu (%) Ag (g/t) Au (g/t) ZnEq (%) AuEq (g/t) Indicated 1.38 3.96 1.15 0.23 128 1.41 9.87 8.11 Inferred 0.17 2.11 0.87 0.16 118 0.80 6.73 5.53 TOTAL 1.55 3.76 1.12 0.22 127 1.34 9.53 7.82 Contained Metal 58kt 17kt 3kt 6.3Moz 69koz 147kt 389koz JORC Classification Tonnes (Mt) Grade Zn (%) Pb (%) Cu (%) Ag (g/t) Au (g/t) ZnEq (%) AuEq (g/t) Indicated 3.46 4.88 1.01 0.27 137.00 1.88 11.99 9.29 Inferred 0.62 1.39 0.37 0.10 52.00 1.46 5.03 3.91 TOTAL 4.08 4.35 0.91 0.25 124.00 1.81 10.93 8.47 Contained Metal 177kt 37kt 10kt 16Moz 238koz 445kt 1,110koz JORC Classification Tonnes (Mt) Grade Zinc Equivalent (field = “ZnEq”) (%) = (Au grade (g/t) * (Au price per ounce/31.10348) * Au recovery) + (Ag grade (g/t) * (Ag price per ounce/31.10348) * Ag recovery) + (Cu grade (%) * (Cu price per tonne/100) * Cu recovery) + (Pb grade (%) * (Pb price per tonne/100) * Pb recovery) + (Zn grade (%) * (Zn price per tonne/100) * Zn recovery) / (Zn price per tonne/100 * Zn recovery) The Company confirms that it is not aware of any new information or data that materially affects the information included in the original market announcements and that all material assumptions and technical parameters underpinning the estimates in the relevant market announcements referenced in this release continue to apply and have not materially changed.
